Representative sensors among various sensors that may be included in the sensing unit 140 will be described in more detail.

First, the proximity sensor 141 refers to a sensor that detects the presence or absence of an object approaching a predetermined detection surface or an object present in the vicinity without using a mechanical contact by using an electromagnetic force or infrared rays. The proximity sensor 141 may be disposed at an inner region of the mobile terminal covered by the touch screen described above or near the touch screen.

Examples of the proximity sensor 141 include a transmission photoelectric sensor, a direct reflection photoelectric sensor, a mirror reflection photoelectric sensor, a high frequency oscillation proximity sensor, a capacitive proximity sensor, a magnetic proximity sensor, and an infrared proximity sensor. In the case where the touch screen is capacitive, the proximity sensor 141 may be configured to detect the proximity of the object with the change of the electric field according to the proximity of the conductive object. In this case, the touch screen (or touch sensor) itself may be classified as a proximity sensor.

On the other hand, for convenience of description, the action of allowing the object to be recognized without being in contact with the touch screen so that the object is located on the touch screen is referred to as "proximity touch", and the touch The act of actually touching an object on the screen is called a "contact touch." The position where an object is in close proximity touch on the touch screen means a position where the object is perpendicular to the touch screen when the object is in close proximity touch. The proximity sensor 141 may detect a proximity touch and a proximity touch pattern (for example, a proximity touch distance, a proximity touch direction, a proximity touch speed, a proximity touch time, a proximity touch position, and a proximity touch movement state). have.

Meanwhile, the controller 180 processes data (or information) corresponding to the proximity touch operation and the proximity touch pattern detected through the proximity sensor 141 as described above, and further, provides visual information corresponding to the processed data. It can be output on the touch screen. Furthermore, the controller 180 may control the mobile terminal 100 to process different operations or data (or information) according to whether the touch on the same point on the touch screen is a proximity touch or a touch touch. .

The touch sensor applies a touch (or touch input) applied to the touch screen (or display unit 151) using at least one of various touch methods such as a resistive film method, a capacitive method, an infrared method, an ultrasonic method, and a magnetic field method. Detect.

As an example, the touch sensor may be configured to convert a change in pressure applied to a specific portion of the touch screen or capacitance generated at the specific portion into an electrical input signal. The touch sensor may be configured to detect a position, an area, a pressure at the touch, a capacitance at the touch, and the like, when the touch object applying the touch on the touch screen is touched on the touch sensor. Here, the touch object is an object applying a touch to the touch sensor and may be, for example, a finger, a touch pen or a stylus pen, a pointer, or the like.

As such, when there is a touch input to the touch sensor, the corresponding signal (s) is sent to the touch controller. The touch controller processes the signal (s) and then transmits the corresponding data to the controller 180. As a result, the controller 180 can determine which area of the display unit 151 is touched. Here, the touch controller may be a separate component from the controller 180 or may be the controller 180 itself.

The controller 180 may perform different control or perform the same control according to the type of the touch object, which touches the touch screen (or a touch key provided in addition to the touch screen). Whether to perform different control or the same control according to the type of the touch object may be determined according to the operation state of the mobile terminal 100 or an application program being executed.

The ultrasonic sensor may recognize location information of a sensing object using ultrasonic waves. On the other hand, the controller 180 can calculate the position of the wave generation source through the information detected from the optical sensor and the plurality of ultrasonic sensors. The position of the wave source can be calculated using the property that light is much faster than ultrasonic waves, i.e., the time that the light reaches the optical sensor is much faster than the time when the ultrasonic wave reaches the ultrasonic sensor. More specifically, the position of the wave generation source may be calculated using a time difference from the time when the ultrasonic wave reaches the light as the reference signal.

On the other hand, the camera 121, which has been described as the configuration of the input unit 120, includes at least one of a camera sensor (eg, CCD, CMOS, etc.), a photo sensor (or an image sensor), and a laser sensor.

The camera 121 and the laser sensor may be combined with each other to detect a touch of a sensing object on a 3D stereoscopic image. The photo sensor may be stacked on the display element, which is configured to scan the movement of the sensing object in proximity to the touch screen. More specifically, the photo sensor mounts a photo diode and a transistor (TR) in a row / column and scans contents mounted on the photo sensor by using an electrical signal that varies according to the amount of light applied to the photo diode. That is, the photo sensor calculates coordinates of the sensing object according to the amount of change of light, and thus the position information of the sensing object can be obtained.

The display unit 151 displays (outputs) information processed by the mobile terminal 100. For example, the display unit 151 may display execution screen information of an application program driven in the mobile terminal 100 or user interface (UI) and graphical user interface (GUI) information according to the execution screen information. .

Electronic paper can change information by using twist balls or electrophoresis using capsules.

In a state where the flexible display unit 251 is not deformed (for example, a state having an infinite curvature radius, hereinafter referred to as a first state), the display area of the flexible display unit 251 becomes flat. In the state deformed by the external force in the first state (for example, a state having a finite radius of curvature, hereinafter referred to as a second state), the display area may be a curved surface. As shown, the information displayed in the second state may be visual information output on a curved surface.

In general, the mobile terminal 400 may include features of or similar to that of the mobile terminal 100 of FIGS. 1A-1C.

The frame part is supported by the head, and provides a space for mounting various components. As illustrated, electronic components such as the control module 480, the sound output module 452, and the like may be mounted in the frame unit. In addition, a lens 403 covering at least one of the left eye and the right eye may be detachably mounted to the frame part.

The control module 480 is configured to control various electronic components provided in the mobile terminal 400. The control module 480 may be understood as a configuration corresponding to the controller 180 described above. In this figure, the control module 480 is illustrated to be installed in the frame portion on one side head. However, the position of the control module 480 is not limited thereto.

The display unit 451 may be implemented in the form of a head mounted display (HMD). The HMD type is a display method mounted on the head and showing an image directly in front of the user's eyes. When the user wears the glass type mobile terminal 400, the display unit 451 may be disposed to correspond to at least one of the left eye and the right eye so as to provide an image directly in front of the user's eyes. In this figure, the display unit 451 is located at a portion corresponding to the right eye so that an image can be output toward the right eye of the user.

The display unit 451 may project an image to the eyes of a user using a prism. In addition, the prism can be formed translucent so that the user can see the projected image and the general field of view in front (the range the user sees through the eye) together.

As such, the image output through the display unit 451 may be viewed by overlapping with the general field of view. The mobile terminal 400 may provide an augmented reality (AR) that displays a single image by superimposing a virtual image on a real image or a background using the characteristics of the display.

The camera 421 is disposed adjacent to at least one of the left eye and the right eye, and is formed to capture an image of the front. Since the camera 421 is located adjacent to the eye, the camera 421 may acquire a scene viewed by the user as an image.

In this figure, the camera 421 is illustrated in the control module 480, but is not necessarily limited thereto. The camera 421 may be installed in the frame unit, or may be provided in plural to acquire a stereoscopic image.

The glass type mobile terminal 400 may include user input units 423a and 423b operated to receive a control command. The user input units 423a and 423b may be adopted in any manner as long as the user is operating in a tactile manner such as touch or push. In the drawing, the frame unit and the control module 480 are provided with push and touch input user input units 423a and 423b, respectively.

In addition, the glass-type mobile terminal 400 may be provided with a microphone (not shown) for receiving sound and processing it as electrical voice data and a sound output module 452 for outputting sound. The sound output module 452 may be configured to transmit sound in a general sound output method or a bone conduction method. When the sound output module 452 is implemented in a bone conduction manner, when the user wears the mobile terminal 400, the sound output module 452 is in close contact with the head and vibrates the skull to transmit sound.

Next, a communication system that can be implemented through the mobile terminal 100 according to the present invention will be described.

First, the communication system may use different air interfaces and / or physical layers. For example, a radio interface that can be used by a communication system includes frequency division multiple access (FDMA), time division multiple access (TDMA), and code division multiple access (CDMA). ), Universal Mobile Telecommunications Systems (UMTS) (especially Long Term Evolution (LTE), Long Term Evolution-Advanced (LTE-A)), Global System for Mobile Communications (GSM), etc. This may include.

Hereinafter, for convenience of explanation, the description will be limited to CDMA. However, it is apparent that the present invention can be applied to any communication system including an orthogonal frequency division multiplexing (OFDM) wireless communication system as well as a CDMA wireless communication system.

The CDMA wireless communication system includes at least one terminal 100, at least one base station (Base Station, BS (also referred to as Node B or Evolved Node B)), and at least one Base Station Controllers (BSCs). ), And may include a mobile switching center (MSC). The MSC is configured to connect with a Public Switched Telephone Network (PSTN) and BSCs. The BSCs may be connected to the BS through a backhaul line. The backhaul line may be provided according to at least one of E1 / T1, ATM, IP, PPP, Frame Relay, HDSL, ADSL, or xDSL. Thus, a plurality of BSCs can be included in a CDMA wireless communication system.

Each of the plurality of BS may include at least one sector, and each sector may include an omnidirectional antenna or an antenna pointing in a radial direction from the BS. In addition, each sector may include two or more antennas of various types. Each BS may be configured to support a plurality of frequency assignments, and the plurality of frequency assignments may each have a specific spectrum (eg, 1.25 MHz, 5 MHz, etc.).

The intersection of sectors and frequency assignments may be called a CDMA channel. BSs may be called Base Station Transceiver Subsystems (BTSs). In this case, one BSC and at least one BS may be collectively referred to as a "base station". The base station may also indicate “cell site”. Alternatively, each of the plurality of sectors for a particular BS may be called a plurality of cell sites.

The broadcast transmitter (BT) transmits a broadcast signal to the terminals 100 operating in the system. The broadcast receiving module 111 illustrated in FIG. 1A is provided in the terminal 100 to receive a broadcast signal transmitted by BT.

In addition, the CDMA wireless communication system may be associated with a global positioning system (GPS) for identifying the location of the mobile terminal 100. The satellite 300 helps to locate the mobile terminal 100. Useful location information may be obtained by up to two or more satellites. Here, the location of the mobile terminal 100 may be tracked using all the technologies capable of tracking the location as well as the GPS tracking technology. In addition, at least one of the GPS satellites may optionally or additionally be responsible for satellite DMB transmission.

The location information module 115 provided in the mobile terminal is used to detect, calculate, or identify the location of the mobile terminal. Examples of the location information module 115 may include a Global Position System (GPS) module and a Wireless Fidelity (WiFi) module. If necessary, the location information module 115 may perform any function of other modules of the wireless communication unit 110 to substitute or additionally obtain data regarding the location of the mobile terminal.

The GPS module 115 calculates distance information and accurate time information away from three or more satellites, and then applies triangulation to the calculated information to accurately calculate three-dimensional current position information according to latitude, longitude, and altitude. can do. Currently, a method of calculating position and time information using three satellites and correcting the error of the calculated position and time information using another satellite is widely used. In addition, the GPS module 115 may calculate speed information by continuously calculating the current position in real time. However, it is difficult to accurately measure the position of the mobile terminal using the GPS module in the shadow area of the satellite signal such as indoors. Accordingly, in order to compensate for GPS positioning, a WPS (WiFi Positioning System) may be utilized.

The Wi-Fi Positioning System (WPS) is a mobile terminal 100 using a WiFi module provided in the mobile terminal 100 and a wireless access point (AP) for transmitting or receiving a wireless signal with the WiFi module. As a technology for tracking the location of a network, this refers to a WLAN (Wireless Local Area Network) based location positioning technology using WiFi.

The Wi-Fi location tracking system may include a Wi-Fi location server, a mobile terminal 100, a wireless AP connected to the mobile terminal 100, and a database in which any wireless AP information is stored.

The mobile terminal 100 connected to the wireless AP may transmit a location information request message to the Wi-Fi location server.

The Wi-Fi positioning server extracts the information of the wireless AP connected to the mobile terminal 100 based on the location information request message (or signal) of the mobile terminal 100. Information of the wireless AP connected to the mobile terminal 100 may be transmitted to the Wi-Fi positioning server through the mobile terminal 100 or transmitted from the wireless AP to the Wi-Fi positioning server.

Based on the location information request message of the mobile terminal 100, the extracted information of the wireless AP is MAC Address, Service Set IDentification (SSID), Received Signal Strength Indicator (RSSI), Reference Signal Received Power (RSRP), RSRQ ( It may be at least one of Reference Signal Received Quality, Channel Information, Privacy, Network Type, Signal Strength, and Noise Strength.

As described above, the Wi-Fi positioning server receives the information of the wireless AP connected to the mobile terminal 100, and extracts the wireless AP information corresponding to the wireless AP to which the mobile terminal is connected from the pre-built database. At this time, the information of any wireless AP stored in the database is MAC address, SSID, channel information, Privacy, Network Type, latitude and longitude coordinates of the wireless AP, the building name, the number of floors, indoor detailed location information (GPS coordinates) Available), the AP owner's address, telephone number, and the like. In this case, in order to remove the wireless AP provided by the mobile AP or the illegal MAC address during the positioning process in the positioning process, the Wi-Fi positioning server may extract only a predetermined number of wireless AP information in the order of high RSSI.

Thereafter, the Wi-Fi location server may extract (or analyze) location information of the mobile terminal 100 using at least one piece of wireless AP information extracted from a database. The location information of the mobile terminal 100 is extracted (or analyzed) by comparing the included information with the received wireless AP information.

As a method for extracting (or analyzing) the location information of the mobile terminal 100, a cell-ID method, a finger print method, a triangulation method, a landmark method, or the like may be utilized.

The Cell-ID method is a method of determining a location of a mobile AP having the strongest signal strength among neighboring wireless AP information collected by the mobile terminal. The simple implementation, no additional cost, and quick location information can be obtained. However, the low installation density of the wireless AP reduces the positioning accuracy.

The fingerprint method collects signal strength information by selecting a reference location in a service area and estimates a location based on signal strength information transmitted from a mobile terminal based on the collected information. In order to use the fingerprint method, it is necessary to database the propagation characteristics in advance.

The triangulation method calculates the position of the mobile terminal based on the coordinates of at least three wireless APs and the distance between the mobile terminals. In order to measure the distance between the mobile terminal and the wireless AP, the signal strength is converted into distance information, the time at which the radio signal is transmitted (Time of Arrival, ToA), and the time difference at which the signal is transmitted (TDoA). , Angle of signal transmission (Angle of Arrival, AoA) and the like can be used.

The landmark method is a method of measuring the location of a mobile terminal using a landmark transmitter that knows the location.

In addition to the methods listed, various algorithms may be utilized as a method for extracting (or analyzing) location information of the mobile terminal.

The extracted location information of the mobile terminal 100 is transmitted to the mobile terminal 100 through the Wi-Fi positioning server, the mobile terminal 100 can obtain the location information.

The mobile terminal 100 may obtain location information by being connected to at least one wireless AP. In this case, the number of wireless APs required to obtain location information of the mobile terminal 100 may be variously changed according to a wireless communication environment in which the mobile terminal 100 is located.

As described above with reference to FIG. 1A, a mobile terminal according to the present invention includes Bluetooth ™, Radio Frequency Identification (RFID), Infrared Data Association (IrDA), Ultra Wideband (UWB), ZigBee, and NFC (Near). Local area communication technologies such as Field Communication (Wireless Communication) and Wireless USB (Wireless Universal Serial Bus) may be applied.

Among these, the NFC module provided in the mobile terminal supports contactless short-range wireless communication between terminals at a distance of about 10 cm. The NFC module may operate in any one of a card mode, a reader mode, and a P2P mode. In order for the NFC module to operate in a card mode, the mobile terminal 100 may further include a security module for storing card information. The security module may be a physical medium such as a universal integrated circuit card (UICC) (for example, a subscriber identification module (SIM) or a universal SIM (USIM)), a secure micro SD, and a sticker, or a logical medium embedded in a mobile terminal ( For example, it may be an embedded SE (Secure Element). Data exchange based on SWP (Single Wire Protocol) may be performed between the NFC module and the security module.

When the NFC module is operated in the card mode, the mobile terminal can transmit the stored card information to the outside like a conventional IC card. Specifically, when the mobile terminal storing the card information of the payment card such as a credit card or bus card is close to the fare payment machine, the mobile short-range payment can be processed, and the mobile terminal storing the card information of the access card is approved for access. Close to the aircraft, the entry process can be initiated. Cards such as credit cards, transportation cards, and access cards may be mounted in a security module in the form of an applet, and the security module may store card information about the mounted card. Here, the card information of the payment card may be at least one of a card number, balance, and usage history, and the card information of the access card may include at least one of a user's name, number (eg, student's student number or company number), and access history. It can be one.

When the NFC module is operated in the reader mode, the mobile terminal may read data from an external tag. In this case, the data received by the mobile terminal from the tag may be coded in a data exchange format (NFC Data Exchange Format) determined by the NFC forum. In addition, the NFC Forum defines four record types. Specifically, the NFC forum defines four record type definitions (RTDs) such as smart poster, text, uniform resource identifier (URI), and general control. If the data received from the tag is a smart poster type, the controller may execute a browser (eg, an Internet browser). If the data received from the tag is a text type, the controller may execute a text viewer. When the data received from the tag is a URI type, the controller executes a browser or makes a phone call, and when the data received from the tag is a general control type, the controller may execute an appropriate operation according to the control content.

When the NFC module is operated in a peer-to-peer mode, the mobile terminal may perform P2P communication with another mobile terminal. At this time, LLCP (Logical Link Control Protocol) may be applied to P2P communication. A connection may be created between the mobile terminal and another mobile terminal for P2P communication. In this case, the generated connection may be classified into a connectionless mode in which one packet is exchanged and terminated, and a connection-oriented mode in which packets are continuously exchanged. Through P2P communication, data such as electronic business cards, contact information, digital photos, URLs, and setup parameters for Bluetooth and Wi-Fi connection can be exchanged. However, since the available distance of NFC communication is short, the P2P mode may be effectively used for exchanging small data.

Hereinafter, embodiments related to a control method that can be implemented in the mobile terminal configured as described above will be described with reference to the accompanying drawings. It is apparent to those skilled in the art that the present invention can be embodied in other specific forms without departing from the spirit and essential features of the present invention.

The second authenticator 570 periodically performs an implicit authentication according to the reception of the continuous authentication request, and determines whether the implicit authentication is successful.

When the implicit authentication succeeds, the second authenticator 570 may transmit an authentication success notification to the authentication controller 530 to inform that the implicit authentication succeeds.

The authentication controller 530 may maintain the authentication as the authentication success notification is received.

If the implicit authentication fails, the second authenticator 570 may transmit an authentication failure notification indicating that the implicit authentication failed to the authentication controller 530.

The authentication controller 530 may release the authentication upon receiving the authentication failure notification.

Thereafter, the authentication controller 530 may transmit an authentication release notification indicating that authentication has been released to the authentication application manager 510.

6 is a flowchart illustrating a method of operating a mobile terminal according to an embodiment of the present invention.

Referring to FIG. 6, the authentication application manager 510 transmits the received authentication information to the authentication controller 530 according to an authentication request of a user (S601).

Here, the specific function may be a function of releasing security, such as unlocking.

In an embodiment, the explicit authentication procedure may be a procedure for performing authentication through matching with pre-registered biometric information, such as a user's fingerprint, a user's iris, a user's face, a user's heartbeat, and the like.

Explicit authentication procedures may further include password authentication to perform authentication through input of certain numbers or letters.

In one embodiment, the implicit authentication procedure may be an authentication procedure for identifying a user based on collected data using artificial intelligence, such as machine learning.

Specifically, the implicit authentication procedure may be a procedure for authenticating a user by using data on a behavior pattern of the user.

An implicit authentication procedure will be described later.

The first authenticator 550 determines whether the explicit authentication succeeds by using the authentication information included in the explicit authentication request of the authentication controller 530, and according to the determination result. Explicit A notification of whether the increase is successful is transmitted to the authentication controller 530 (S605).

When explicit authentication succeeds, the first authenticator 550 may transmit a notification to the authentication controller 530 indicating that the explicit authentication succeeds. The notification informing that the explicit authentication is successful may trigger a registration procedure for the implicit authentication.

When explicit authentication fails, the first authenticator 550 may transmit a notification to the authentication controller 530 indicating that explicit authentication has failed.

The authentication control unit 530 authenticates the notification on whether the explicit authentication succeeds. application  It transmits to the management unit 510 (S607).

When it is determined that explicit authentication is successful, the authentication application manager 510 may output a notification indicating that the explicit authentication is successful through the display unit 151 or the sound output unit 152.

If it is determined that the explicit authentication has failed, the authentication application manager 510 may output a notification indicating that the explicit authentication has failed through the display unit 151 or the sound output unit 152.

If explicit authentication succeeds, the authentication controller 530 transmits an Enroll start request for implicit authentication to the second authenticator 570 (S609).

The second authenticator 570 performs a registration procedure according to the received registration start request (S611).

The second authenticator 570 may perform a registration procedure for implicit authentication according to the registration start request received from the authentication controller 530.

In one embodiment, the registration procedure for implicit authentication may be a procedure of collecting user behavior patterns for a period of time before and after explicit authentication is performed.

The period of time may be from 1 minute to 5 minutes before and after explicit authentication is performed, but this is only an example. The period of time may be set as a default or may be set differently according to a user input.

The behavior pattern of the user may be a behavior pattern taken before and after the user performs an explicit authentication procedure.

For example, the behavior pattern of the user may include one or more of whether the user is holding the mobile terminal 100, a direction of the user's gaze, and a walking pattern of the user before and after performing an explicit authentication procedure.

The second authenticator 570 may collect a user behavior pattern for a period of time for implicit authentication before or immediately after the explicit authentication is performed.

The collected user behavior pattern may be stored in the memory 170.

The second authenticator 570 may collect first data on whether the user is holding the mobile terminal 100 through the gyro sensor before and after the user performs an explicit authentication procedure.

The touch input speed of the keyboard may be an average speed of the touch input speeds collected during the predetermined period.

The second authenticator 570 may store the collected first to fourth data in the memory 170 for implicit authentication.

The stored first to fourth data may be data used as a reference for determining whether to maintain continuous authentication later.

When the registration process is finished, the second authenticator 570 may perform an implicit authentication. Registration has ended  The notification transmits a registration end notification to the authentication control unit 530 (S613).

In response to receiving the registration end notification, the authentication controller 530 periodically transmits a continuous authentication request for performing implicit authentication to the second authentication unit 570 (S615).

The continuous authentication request may be a request sent to determine whether to maintain authentication for a specific function of the mobile terminal 100. For example, the persistent authentication request may be a request sent to determine whether to maintain an unlocked state or change to a locked state that restricts a specific function of the mobile terminal 100.

The second authenticator 570 periodically performs implicit authentication according to the reception of the continuous authentication request (S617), and determines whether the implicit authentication is successful (S619).

In one embodiment, the second authenticator 570 may re-collect the user behavior pattern as the continuous authentication request is received.

The second authenticator 570 may determine whether the re-collected user behavior pattern and the pre-registered user behavior pattern match.

If the re-collected user behavior pattern and the pre-registered user behavior pattern match, the second authenticator 570 may determine that the implicit authentication is successful.

In one embodiment, the second authenticator 570 implicitly, if each of the plurality of behavior items included in the re-collected user behavior pattern matches each of the plurality of behavior items included in the registered user behavior pattern It can be determined that authentication is successful.

The plurality of action items may include a first action item indicating a state in which the user is holding the mobile terminal 100, a second action item indicating whether the user's gaze direction is facing the front of the display unit 151, and a touch input speed of the keyboard. It may include a third action item including a.

The second authenticator 570 may determine that the user behavior patterns match when each of the newly collected first to third action items matches each of the registered first to third action items.

That is, the second authentication unit 570 may determine that the implicit authentication is successful when each of the newly collected first to third action items matches each of the registered first to third action items. .

In another embodiment, when the second authentication unit 570 matches any one of the newly collected first to third action items corresponding to any of the registered first to third action items corresponding thereto. In other words, it can be judged that the implicit authentication is successful.

In another embodiment, the second authenticator 570 may include two of the newly collected first to third action items and two of the registered first to third action items respectively corresponding thereto. If there is a match, it can be determined that the implicit authentication is successful.

If the re-collected user behavior pattern does not match the pre-registered user pattern, the second authenticator 570 may determine that the implicit authentication has failed.

When the implicit authentication succeeds, the second authenticator 570 transmits an authentication success notification to the authentication controller 530 informing that the implicit authentication succeeds (S621).

The authentication control unit 530 maintains authentication in response to receiving the authentication success notification (S623).

In one embodiment, maintaining the authentication may represent maintaining the unlocked state of the mobile terminal 100.

In another embodiment, maintaining authentication may indicate maintaining a login state of a particular application.

After maintaining the authentication, the authentication controller 530 may transmit a continuous authentication request to the second authentication unit 570 again after a predetermined time. That is, in the process of maintaining authentication, the authentication controller 530 periodically transmits a continuous authentication request to the second authentication unit 570 to perform an implicit authentication procedure.

When the implicit authentication fails, the second authenticator 570 transmits an authentication failure notification indicating that the implicit authentication has failed to the authentication controller 530 (S625).

For example, the authentication controller 530 may change the unlock state of the mobile terminal 100 to the locked state when receiving the authentication failure notification.

Thereafter, the authentication control unit 530 authenticates the authentication release notification indicating that authentication has been released. application  The control unit 510 transmits the data to the management unit 510 (S629).

The authentication application manager 510 may display that authentication is released through the display unit 151.

Meanwhile, according to an embodiment of the present disclosure, whenever an explicit authentication is performed, the authentication controller 530 may update data necessary for implicit authentication.

For example, first, explicit authentication is performed, the keyboard input speed registered for the success of implicit authentication was the first speed, and second and third, explicit authentication is performed, and for implicit authentication, registration Assume that the input keyboard speed is changed to the second speed.

The second authenticator 570 may update the keyboard input speed registered for the implicit authentication from the first speed to the second speed. That is, the second authentication unit 570 may re-register the action item when the action item of the keyboard input speed is changed more than a predetermined number of times.

Subsequently, after the explicit authentication, the second authenticator 570 may determine whether the implicit authentication succeeds based on the re-registered keyboard input speed for implicit authentication.

A diagram illustrating the combined authentication procedure.

Referring to FIG. 7, one or two registration procedures are required for explicit authentication.

For example, when performing explicit authentication using a password, a registration procedure is required in which the user enters the password once or twice.

After registration of the password, in order to pass explicit authentication later, the user must enter a previously registered password.

Referring to FIG. 8, an implicit authentication procedure is shown.

Implicit authentication requires the registration of user behavior patterns. User behavior patterns have already been described.

When the user behavior pattern is registered, the second authenticator 570 may periodically perform an implicit authentication procedure. The period for performing the implicit authentication procedure may be 5 seconds, but this is only an example.

That is, the second authenticator 570 may determine whether the registered user behavior pattern matches the newly collected user behavior pattern.

The second authenticator 570 may maintain an authentication state when the registered user behavior pattern and the newly collected user behavior pattern match.

Referring to FIG. 9, a hybrid authentication procedure combining explicit authentication and implicit authentication according to an embodiment of the present invention is illustrated.

First, the authentication controller 530 may perform a registration procedure 910 for explicit authentication.

Thereafter, the authentication controller 530 may receive authentication information for explicit authentication and perform an explicit authentication procedure 930 according to the received authentication information.

The authentication control unit 530 registers the registration process 951 for the first user behavior pattern before performing the explicit authentication procedure 930 or the registration procedure 953 for the second user behavior pattern after performing the explicit authentication procedure 930. ) Can be performed.

Thereafter, the second authenticator 570 may compare the previously registered first user behavior pattern or the previously registered second user behavior pattern with the newly collected user behavior pattern.

The second authenticator 570 may perform the periodic implicit authentication procedure 970 according to the comparison result.

If the previously registered user behavior pattern matches the newly collected user behavior pattern, the second authenticator 570 may determine that the implicit authentication succeeds and maintain the authentication state.

When there is a mismatch between the previously registered user behavior pattern and the newly collected user behavior pattern, the second authenticator 570 may determine that the implicit authentication has failed and release the authentication state.
